Lambeth Bridge and Westminster Bridge in London are visible, as are the Houses of Parliament, Big Ben and the Millennium Wheel in this file image from 2006.

A bus has exploded in central London — but this time it's only for a movie.

City officials Sunday reassured the public that the explosion was a movie stunt for "The Foreigner" starring Jackie Chan and Pierce Brosnan.

The sight of the bus in flames and the twisted wreckage afterward caused consternation on Twitter from London residents who said the public had not been adequately warned about the stunt. Some complained that children had been frightened by the blast.

It reminded some of the 2005 attack on London's transport system that killed 52 civilians. That attack included the explosion of a bus in central London.

The Port of London Authority said Lambeth Bridge had been closed to the public prior to the stunt.
